Hi there,I'm not entirely clear about what you want, but I'll have a stab at a couple of possible solutions that might be of use:

1) If you simply want to be able to display a random image then just add the 5 images as frames to a sprite and use this action:

>set object frame to floor(random(5))

...to display a random image. In this situation you don't need to worry about the names of the images. You will need to ensure the animation speed is set to zero, or that you have stopped the animation to stop it playing through all the frames.

2) If you need to keep the image names (for some reason), and want to randomise the images and ensure that they keep that randomised pattern without repetition of images until all images have displayed:

i) add each image as a separate animation to a sprite, naming each animation after the imageii) add the animation names to an Array object then shuffle the array using a method such as this one:
